Scientific paper

Using the integral field unit of X-shooter at VLT, we have recovered the first velocity fields of GRB host galaxies at redshift <0.6. This facility is able to recover not only the velocity fields from almost all emission lines thanks to an unrivaled wavelength coverage, but also to recover maps of physical properties. We present the preliminary analysis of X-shooter/IFU observations dedicated to the study of GRB host galaxies undertaken in the frame of the Italian-French GTO program. Our goal is to understand the physical processes at the origin of the GRB by analyzing in detail the spatial distributions of the kinematics, metallicities, extinction, star-formation, and how they are inter-related.
